Which tRNA molecule would attach to the mRNA strand?
C&G can only pair up ,and U&A can only pair up.
What are the base sequences in trna?
Anticodons
Which mutation cannot occur in a tRNA encoding gene?
nonsense mutation
How can the wobble hypothesis affect the anticodon and the amino acids?
The wobble hypothesis concerns the codons in mRNA and anticodons in tRNA. The initial two tRNA bases behave in a restricted manner, only binding with complementary mRNA bases (A-U and G-C). The third tRNA base can behave in a different manner (the "wobble" effect) and bind in an unlimited manner to any base on the third position of the mRNA codon. As a result, the amino acids created by the ribosomes by the triplet pairing in translation may vary more dramatically in these instances and, in turn, the amino acids produced may have more variation.
What happens to the amino acids in the chain if the fourth base is changed in the DNA?
TRNA
What is translation when speaking of protein synthesis?
tRNA is changed into amino acids following nitrogen base pairing rules.
Why is specific base pairing essential to the process of transcription and translation?
During transcription, an mRNA (also called a gene message or a messenger RNA) is produced using DNA as the template. The gene on the DNA has specific sequences that are transcribed and this process heavy relies on base pairing interactions between the DNA and RNA as wells as between DNA and the proteins that initiate transcription During translation, the mRNA or the genetic message is translated into proteins. This is done by structures called ribosomes. The ribosomes bind mRNA and recruit tRNA that contain the building blocks of proteins called amino acids. The tRNA molecules recognize groups of three nucleotides on the mRNA called codons and protein synthesis (the order in which the amino acids are assembled) is dependent on base pairing between the tRNA and mRNA For these reasons, specific base pairing is essential to transcription and translation

What types of RNA are involved in protein synthes?
Messenger RNA (mRNA) copies the DNA template and carries it to a ribosome, composed of ribosomal RNA (rRNA) and proteins. At the ribosome, transfer RNA (tRNA) brings amino acids from the cytoplasm and the amino acid is placed in its correct place, according to the complementary base-pairing between an mRNA codon and the tRNA anticodon.
Which mutation cannot occur in a tRNA encoding gene?
nonsense mutation
What is the pairing mRNA and tRNA to make a protein that occurs in which organelles?
The process is translation which occurs in ribosomes which are often attached to the rough endoplasmic reticulum (in eukaryotes).
Base triplet on tRNA recognizing complementary base triplet on mRNA?
anticodon.
Where does initiation of translation occur?
An initiation complex for translation forms by the assembly of the ribosomal subunits and initiator tRNA (met-tRNA) at the start codon on the mRNA.
